3. TO THREAD THE BOBBIN CASE
Before threading the bobbin case, study Fig, 5, 6, 7,
to get a general idea as to how it is done.
(1) Hold the bobbin case with your left hand and
put the bobbin into the bobbin case with your
right, leaving about two inches of the thread
end unwound (Fig. 5). As the bobbin is being
inserted in the bobbin case, the THREAD FLOW,
you will note, is CLOCKWISE (Fig. 5).
(2) While holding the bobbin case os before, grasp
the thread end with your right hand, guide it
into the cross slot (Fig. 6).
(3) Then pull it through under the tension spring of
the bobbin case (Fig. 6) until it enters the de­
livery eye (Fig. 7).
